Is Huawei's mobile phone fast charging protocol QC or PD?

No, the Huawei mobile phone fast charging protocol is "SCP/FCP". Huawei mobile phones have two fast charging protocols, FCP and SCP. In the early days, Huawei used the FCP fast charging protocol, which has the characteristics of high voltage and low current; while SCP is the super fast charging that was launched later and supports two output powers, namely 22.5 W fast charging and 40W fast charging, the voltage and current are 4.5V/5A or greater than 5V4.5A, and a super fast charging reminder will be displayed during charging.

In order to pursue a better mobile phone battery life experience, in addition to increasing battery capacity, charging speed is also an aspect that affects the experience, and this also causes the charging power of mobile phones to continue to increase. Now the charging power of commercial mobile phones has reached With 120W, the phone can be fully charged in as little as 15 minutes.

It is undeniable that high-power chargers do bring faster charging speeds to mobile phones. However, due to the different fast charging protocols adopted by different manufacturers, the fast charging protocols of each manufacturer are also relatively confusing. If you want To experience fast charging, you must use original chargers and charging cables. Not only does charging become troublesome, but it also makes extra chargers at home a waste.

The fast charging protocols currently on the market mainly include Huawei SCP/FCP fast charging protocol, Qualcomm QC protocol (representing Xiaomi mobile phone), PD protocol (representing mobile phone iPhone), OPPO VOOC flash charging and VIVO Flash Charge.

Huawei SCP/FCP fast charging protocol

FCP and SCP are both fast charging protocols launched by Huawei. Fast charging of mobile phones has been available for several years, and Huawei also has Two fast charging protocols.

The full name of Huawei’s SCP fast charging protocol is Super Charge Protocol, while the full name of FCP fast charging protocol is Fast Charge Protocol. In the early days, Huawei used the FCP fast charging protocol, which has the characteristics of high voltage and low current. For example, the early 9V2A 18W was used on Huawei Mate8 mobile phone. Later, it will be upgraded to the SCP protocol to achieve fast charging in the form of high current.

To put it simply, FCP is fast charging, which was launched earlier and supports an output power of 18W fast charging and 9V/2A. SCP is a super fast charge introduced later. It supports two output powers, namely 22.5W fast charge and 40W fast charge. The voltage and current are 4.5V/5A or greater than 5V4.5A. When charging, it will remind you of the super fast charge. .

Qualcomm QC Agreement

The full name of Qualcomm QC Agreement is Quick Charge. Currently, mobile phones equipped with Snapdragon processors are on the market. Basically all support the fast charging protocol. Initially, the QC1 protocol supports 10W fast charging, QC3 supports 18W, and QC4 has passed USB-PD certification. At the current QC5 stage, the charging power can reach 100W. It is worth mentioning that the QC fast charging protocol currently supports the USB-PD fast charging standard, which also means that chargers using the USB-PD fast charging protocol can directly charge iOS and Android dual-platform devices.

VOOC flash charging

OPPO can be said to be the first mobile phone manufacturer in China to start fast charging of mobile phones. The early "Charging 5" Minutes, 2 hours of talk” slogan is still familiar to this day. VOOC1.0 fast charging was released in 2014. The charging power at that time was 20W and has gone through several generations of development and optimization. In 2020, OPPO proposed 125W super flash charging technology. It has to be said that OPPO's fast charging has something to offer. It does not use the Qualcomm QC protocol like other manufacturers, but uses its own VOOC flash charging protocol, which uses a low-voltage, high-current charging solution.

So in the market, everyone has also seen some machines that support 125W fast charging. Among them, realme itself has a close relationship with OPPO, so it supports 125W fast charging. It's also reasonable.

VIVO’s Flash Charge also adopts a dual charge pump and dual cell design. The current maximum charging power has been developed to 20V6A 120W, which can charge a 4000 mAh lithium battery to 50% in 5 minutes. , it can be fully charged in 13 minutes. And now its iQOO models have already taken the lead in commercializing 120W chargers. In terms of mobile phone charging, OPPO and VIVO’s technologies are relatively advanced.

USB-PD fast charging protocol

The full name of USB-PD fast charging protocol is USB Power Delivery, which is a fast charging specification developed by the USB-IF organization , is one of the current mainstream fast charging protocols. Apple is one of the initiators of the USB PD fast charging standard, so now there are Apple mobile phones that support fast charging, and they use the USB-PD fast charging protocol.

The USB-PD fast charging protocol and other fast charging protocols are more like a relationship of inclusion and inclusion. Currently, the USB-PD 3.0 protocol already includes Qualcomm QC 3.0 and QC4.0, Huawei's SCP and FCP, and MTK's PE3.0 and PE2.0, as well as OPPO's VOOC. Therefore, from an overall perspective, the USB-PD fast charging protocol has the advantage of “unifying the world”.

It is precisely because the fast charging of different mobile phone manufacturers is mostly based on their own fast charging protocols, which is relatively confusing and cannot bring the convenience of fast charging to users. Therefore, not long ago, Huawei, OPPO, VIVO, Xiaomi and other manufacturers took the lead in launching a "Mobile Terminal Integrated Fast Charging Technical Specification", aiming to solve the problem of fast charging compatibility. Once the problem is solved, users will only need to Using one fast-charging charger, you can achieve a fast-charging experience for terminal devices of different brands.

For consumers, mobile phone compatible and consistent convenient charging is the charging experience we want, and once the fast charging protocols of different mobile phone manufacturers are opened, it will undoubtedly reduce the number of chargers used, and at the same time It is also an environmentally friendly measure. Compared with the iPhone not distributing a charger, achieving fast charging compatibility of the charger is a powerful and feasible measure for environmental protection.
